cognitive dissonance & self-justification

Cognitive dissonance 

The psychological discomfort we feel when our behaviors and beliefs are inconsistent.

Example of cognitive dissonance

A person who values health but smokes may feel tension between their actions and beliefs.

Ways to reduce cognitive dissonance

Change behavior, change attitude, or add new cognitions to justify behavior.

Self-justification

The process of explaining one’s actions to reduce feelings of dissonance.

Insufficient justification effect

When people justify behavior internally because external rewards or pressures are insufficient.

Effort justification

The tendency to increase liking for something we worked hard to attain.

Example of effort justification

A person who endures hazing to join a group may value membership more highly.

Post-decision dissonance

The discomfort after making a choice between two attractive options.

How to reduce post-decision dissonance

Emphasize the positives of the chosen option and the negatives of the rejected one.

Hypocrisy induction

Causing dissonance by making people aware of inconsistency between their attitudes and behaviors.

Mild punishment and attitude change 

Smaller punishments lead to internalization of rules due to internal justification.

External justification

A reason or explanation for dissonant behavior outside the individual (e.g., to receive a reward).

Internal justification

Changing one’s attitude or belief to reduce dissonance without external cause.

Example of internal justification

Convincing yourself a boring task was fun because you were only paid $1 to do it.

Counterattitudinal behavior

Acting contrary to one’s beliefs, often leading to attitude change through dissonance.

Cognitive dissonance vs self-perception theory

Dissonance involves tension and motivation to reduce discomfort; self-perception is observing one’s behavior to infer attitudes.

When dissonance is strongest

When the behavior is voluntary and impacts self-concept.

Cultural differences in dissonance

Western cultures focus on individual inconsistency; Eastern cultures emphasize social harmony.

Moral dissonance

The discomfort experienced when actions conflict with moral values.

Real-life example of cognitive dissonance

Buying an expensive item, then justifying it as “worth it” despite doubts.
